Roman Puchkovskiy updated IGNITE-22990:
---------------------------------------
Description:
If
* an operation (an RW read/write or a commit) concerns table T
* index I did not exist in InitialSchema for the transaction
* in the schema corresponding to the operation/commit index I on table T is at
least in the BUILDING state
then the schemas are not compatible.
In other words, we should not allow to commit an RW transaction which started
on a schema before an index was created in the Catalog, but which tries to
commit on a schema where the index was seen to be built.
This will make the mechanism introduced in IGNITE-21017 obsolete and it will
need to be removed. The reason is that the mechanism from IGNITE-21017 is
heavier.
